Police were called to the Cumberland Farms on Route 6 at 12:37 p.m. after reports that a teenager had been struck by a green Honda Accord, driven by Dorothy Herold, 76, of Wellfleet. The 16-year-old, identified as Miles Tibbetts, was not breathing when officers arrived, so CPR was performed.

Tibbetts was transported to Cape Cod Hospital then taken by medical helicopter to Beth Israel Hospital in Boston where he died Sunday.

The exact cause of the crash is under investigation. No charges have been filed.
